Method of playing a keno game of chance with a multiplier bonus payout play option

ABSTRACT

This invention relates to the field of playing a Keno style game of chance which allows a player to potentially multiply its winnings by a factor of up to five (5) times the normal winning ticket payout amount by placing an additional wager on the game. The multiplying factor is determined based on one of the following two methods: (1) comparing the number that is selected on the Nth drawing of the twenty randomly drawn winning numbers to a predetermined multiplier map, or (2) taking the total matching numbers that exist between the twenty randomly drawn winning numbers for that game and the twenty numbers that are contained on a predetermined virtual Keno ticket. The object of the game is to bring additional excitement to the traditional Keno style game by providing the player the chance to win a lot more money if the player should obtain a winning ticket.

BACKGROUND Field of Invention

This invention relates to the field of playing a game of chance such as Keno which allows a player to make a separate wager in addition to the base wager to potentially increase the player's winnings by providing a multiplier option which multiplies the players base winnings by one (1×), two (2×), three (3×), four (4×) or even 5 times (5×).

SUMMARY OF THE INVENTION

The invention is associated with the improvement of the game of chance called Keno which allows a player to make an additional separate wager from the traditional base Keno wager which offers the player the opportunity to multiply the players payout on the base ticket up to five times or even higher up to ten times. The amount of the multiplier can be determined using two different methods. The first method the Multiplier Bonus Payout Factor is determined based upon one of the numbers drawn from the twenty randomly drawn winning numbers. The gaming establishment will pre-determine which randomly drawn winning number will be used to determine Multiplier Bonus Payout Factor (i.e., the first, second, third, fourth, etc.). For example, if the gaming establishment determines that the first randomly drawn winning number will be used to determine the Multiplier Bonus Payout Factor and the number drawn is between 1-40 then the Multiplier Bonus Payout Factor will be One (1×); if the number drawn is between 41-50 then the Multiplier Bonus Payout Factor will be Two (2×); if the number drawn is between 51-60 then the Multiplier Bonus Payout Factor will be three (3×); if the number drawn is between 61-70 then the Multiplier Bonus Payout Factor will be four (4×); and if the number drawn is between 71-80 then the Multiplier Bonus Payout Factor will be five (5×).

The gaming establishment may also change around the number of balls included in determining the Multiplier Bonus Payout Factor based upon the probability of the payout. For example, the gaming establishment can eliminate any One (1×) payouts and have only 2×, 3×, 4× and 5× Multiplier Bonus Payout Factors by doing the following: if the number drawn is between 1-71 then the Multiplier Bonus Payout Factor will be Two (2×); if the number drawn is between 72-74 then the Multiplier Bonus Payout Factor will be three (3×); if the number drawn is between 75-77 then the Multiplier Bonus Payout Factor will be four (4×); and if the number drawn is between 78-80 then the Multiplier Bonus Payout Factor will be five (5×).

The following chart will show you how the probabilities are determined:

SCENARIO 1 Times Number of Balls Probability 1 40 50.00% 2 10 12.50% 3 10 12.50% 4 10 12.50% 5 10 12.50% Base Keno Hold is 25.00%; Average Multiple is 2.25 and Multiplier Hold is 16.6%

SCENARIO 2 Times Number of Balls Probability 1 0 00.00% 2 71 88.75% 3 3 3.75% 4 3 3.75% 5 3 3.75% Base Keno Hold is 25.00%; Average Multiple is 2.225 and Multiplier Hold is 16.6%.

In the second method, Multiplier Bonus Payout Factor is determined based upon the number of matching numbers between the twenty randomly drawn winning numbers and the twenty numbers identified on a pre-selected virtual Keno ticket posted at the gaming site. For example, if the number of matching numbers is between 1-4 then the Multiplier Bonus Payout Factor will be One (1×); if the number drawn is between 5-8 then the Multiplier Bonus Payout Factor will be Two (2×); if the number drawn is between 9-12 then the Multiplier Bonus Payout Factor will be three (3×); if the number drawn is between 13-15 then the Multiplier Bonus Payout Factor will be four (4×); and if the number drawn is between 16-20 then the Multiplier Bonus Payout Factor will be five (5×).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 represents a flow diagram for playing a Keno game of chance with a Multiplier Bonus Payout Play Option (hereinafter “Keno Multiplier Option”). A Player starts the game by selecting between one (1) and twenty (20) numbers from a pool of numbers which typically consist of the numbers one (1) through eighty (80) (10). FIG. 3 depicts a diagram of the eighty numbers which are displayed at the gaming establishment were the Keno game is played which encompasses the numbers that may be selected from by the Player. Player then decides if he wants to place an additional wager on the Keno Multiplier Option of the game (20). The Player then purchases a Keno ticket including the Keno Multiplier Option from the gaming establishment (30) and is given a Keno Ticket from the gaming establishment which contains the numbers selected by the Player (40). After a certain period of time, the gaming establishment will stop selling tickets for that particular Keno Game (50) and then draw the Winning Keno Numbers by randomly drawing twenty numbers from the same pool of numbers (60). The gaming establishment will post the Winning Keno Numbers (70). The Player then matches his numbers on his Keno ticket to the twenty randomly drawn numbers to determine the number of matches he has (90). Based upon the gaming establishment's predetermined rules, the Player determines if he has a winning ticket based upon the number of matches he has (90). If the Player has a winning ticket, his total winnings will be calculated by multiplying his winnings by the Multiplier Bonus Payout Factor (100). Upon presentation of the winning ticket, the Player will be paid his total winnings (110).

FIG. 2 outlines the two means by which the gaming establishment may determine the Multiplier Bonus Payout Factor. In Option One (200), the Multiplier Bonus Payout Factor is determined based upon one of the numbers drawn from the twenty randomly drawn winning numbers. The gaming establishment will pre-determine which randomly drawn winning number will be used to determine Multiplier Bonus Payout Factor (i.e., the first, second, third, fourth, etc.). For example, if the gaming establishment determines that the first randomly drawn winning number will be used to determine the Multiplier Bonus Payout Factor and the number drawn is between 1-40 then the Multiplier Bonus Payout Factor will be One (1×) (201); if the number drawn is between 41-50 then the Multiplier Bonus Payout Factor will be Two (2×) (202); if the number drawn is between 51-60 then the Multiplier Bonus Payout Factor will be three (3×) (203); if the number drawn is between 61-70 then the Multiplier Bonus Payout Factor will be four (4×) (204); and if the number drawn is between 71-80 then the Multiplier Bonus Payout Factor will be five (5×) (205). The reference to the specific numbers drawn and the corresponding Multiplier Bonus Payout Factor identified above is just one example of how the Multiplier Bonus Payout Factor can be determined and this invention is not limited to the arrangement identified above. For example in a separate embodiment, the Multiplier Bonus Payout Factor can be determined as follows: if the gaming establishment determines that the tenth (10^(th)) randomly drawn winning number will be used to determine the Multiplier Bonus Payout Factor and the number drawn is between 1-71 then the Multiplier Bonus Payout Factor will be Two (2×) (206); if the number drawn is between 72-74 then the Multiplier Bonus Payout Factor will be Three (3×) (207); if the number drawn is between 75-77 then the Multiplier Bonus Payout Factor will be three (4×) (208); and if the number drawn is between 78-80 then the Multiplier Bonus Payout Factor will be four (5×) (209).

In another preferred embodiment, Option Two (300), Multiplier Bonus Payout Factor is determined based upon the number of matching numbers between the twenty randomly drawn winning numbers and the twenty numbers identified on a pre-selected virtual Keno ticket posted at the gaming site. For example, if the number of matching numbers is between 1-4 then the Multiplier Bonus Payout Factor will be One (1×) (301); if the number drawn is between 5-8 then the Multiplier Bonus Payout Factor will be Two (2×) (302); if the number drawn is between 9-12 then the Multiplier Bonus Payout Factor will be three (3×) (303); if the number drawn is between 13-15 then the Multiplier Bonus Payout Factor will be four (4×) (304); and if the number drawn is between 16-20 then the Multiplier Bonus Payout Factor will be five (5×) (305).
